Softube has developed DSP-card and software for simulation of the sound of old tube amplifiers. The purpose with this thesis is to design a compact amplifier with high power to function together with the DSP-card and build a unit that can replace several other guitar amplifiers. The advantages with that kind of solution could be that it would be cheaper, easier to carry and easier to stor than the real amplifiers. The amplifier that has been designed is of class D type with digital PWM modulator. There is several types of amplifier modules on the market that use analog input signal, but if one of them would be used a D-A converter is needed on the DSP card.

In this project I have worked with porcelain och and porcelain decors. The project was based on questions like why porcelain is such a richly decorated product and how you can maka a shape and a decor feel like a entirety. In December 2009 I went to China in search for answers and to study porcelain decors. This trip has been my inspiration throughout the whole project and also the main theme for the idea, the shape and the decor. That is why I decided to make a teacup with a plate that also has a function as a lid.As I first started working with the shape I was thinking to make a rounded teacup, inspired by the chinese rice bowls, but since I had to produce the porcelain by myself I decided to make a much more simple shape.

This study was made to compare and distinguish any differences in olfactory recognition and host plant adaptation between two strains of cotton leaf worm, Spodoptera littoralis. The populations used were established in Egypt and Benin, Africa. The documentation consisted of information about (1) each of the strains development through the larval stage up to pupation on diets of cotton, clover and cowpea. (2) Their oviposition preferences as adults between cotton, clover, cowpea, maize and cabbage. (3) Electroantennographic recordings to quantify any possible responses to plant volatiles. Throughout the diet experiments the larvae from the Benin strain showed significantly a better development between artificial, clover, cowpea and cotton respectively, while the Egypt strain had significance between artificial, cotton and cowpea/clover as diet. Also noted was how the strains substantial development of weight differentiated if fed the cotton diet, followed by the cowpea diet showing that the Benin strain would develop a higher body mass on a cotton diet as well as on a cowpea diet. This trend was however switched once the pupal stage was reached, where the Egyptian strain contained a significantly greater body mass than the Benin strain on the artificial and the Benin strain a greater on cowpea, which suggests that in the end, the Benin strain develops significantly better on cowpea while the Egypt strain develops better on an artificial diet. During the oviposition experiment that both stains showed a clear difference in hierarchy of host plants considered suitable for oviposition, where the Egyptian strain is significantly more attracted to clover than the Benin strain. Also showed with electroantennographic recordings and significant values was the higher sensitivity the Egypt strain had towards (E)2-hexenal, (E/Z)-b-ocimene, (Z)-3-hexenyl acetate, Nonanal, (-)-linalool and ?-myrcene when compared to the responses from the Benin strain..

This project is a study in how to represent the Swedish magician and variety artist Carl-Einar Häckner in a web-based environment. With a starting point focusing on illustration I wanted to produce a web environment that would function as a prototype for a webpage. My personal aim was to explore and gain new experiences from working in a digital interactive environment. I wanted to use animation and illustration to create an atmosphere and communicate emotions, and in the end find out a way of how to integrate that with a more text based content. The project is a personal project based on my interpretation of the work of Carl-Einar Häckner and an effort to translate Häckners expression and the emotions he evokes in his variety shows into image..

Full-field flash electroretinography is an electrodiagnostic method used to examine the function of retinal cells. Light stimulation of the eye elicits electrical potentials in the retina. By aid of a corneal electrode and a reference electrode close to the back of the eye, the electrical potentials can be recorded and presented as an electroretinogram (ERG). ERGs driven by mainly one type of cones can be used to examine the function of a single cone class. In human beings, studies have shown the cone class sensitive to light of short wavelengths, the S-cones, to be more vulnerable to acquired damage than the other cone classes (Daley et al., 1987; Gouras et al., 1993; Greenstein et al., 1989). Dogs have two cone classes, S-cones, and M/L-cones (most sensitive to medium to long wavelengths).

Our thesis is conducted in collaboration with Draper Europe AB in Halmstad.The goal of the project has been to construct a baseline concept for the instaling of aprojector screen. Draper Europe AB, in the curent situation, have several kinds of fabrics and designs on their sceens and the cases they are in. Today if you select a screen you can´t chose the design and function of the sceens case.The arrangement of the components inside the cases was to be constructed so the assembler simply could move them to different cases. To make it even easier for the assembler and to save time, the desire of less component was mentioned. Another problem that needed to be solved was the mounting of the projectionscreen at the customer place.

This report is a bachelor's thesis of two students from the Energy and Environment degree at KTH Stockholm. Grinda is an island situated Stockholm archipelago. Skärgårdsstiftelsen is landowners and manages the area. Grinda Wärdshus, a guest house located in the island, currently uses an oil-fired boiler as a heating system. The aim of this thesis is to investigate whether wood chips or pellets is, from a sustainability standpoint, a suitable heating method for the guest house.

In agricultural educations you learn to use different economic planning tools, as basis for decision. The purpose and goal of this work has been to find out if economic planning tools are used by the farmers in Sweden. We choose to do an investigation through personal interviews, and used an inquiry to get as equivalent answers as possible from the farmers. This work contains a literature study with relevant facts about the questions that is brought up in the inquiry. This study of literature explains shortly some different calculation methods and bases for decision. It also contains useable information that is important to know before an investment. The questions that are asked to the farmers have focused on the use of calculation methods and economical planning tools.

The purpose of this paper was to examine how people experience the practice of Cannabis in daily life. The study was based on interviews with five individuals who have experience with cannabis use. They do not represent a bigger population only themselves. We chose these particular individuals because all of them began using cannabis at a young age- everyone before they were twenty. But they have been using cannabis because of different reasons.

In this essay we aim at finding an appropriate flash estimator of the quarterly Swedish private consumption (PK). With the aid of the statistics program TRAMO we study if monthly data from the consumer survey (HIP) and retail industry (DH) can be used in a transfer function model (TFM) to forecast PK. In the work of assessing the state of the market and the business trend, fast information from the national accounts is needed for making decisions for the economic politics in Sweden. A way to speed up the information process is to use leading economic indicators to asses this development. Another way to get information faster is to use a flash estimate.

The base for the study is laid during an internship at a regional office in Brussels. The study initially concentrates on the function and activities of different regional offices located in Brussels, in order to answer the core question.The main focus is to reveal an eventual change of cooperation patterns between different regional offices, and in particular the eventual redirection away from a main cooperation between offices deriving from the same national state.Through an empirical material, based on a series of interviews, an analysis is made using three hypotheses concerning the patterns of cooperation among regional offices.The notion of a coming change stated by, in particular, two older studies is used as a theoretical steppingstone with the conclusion that a change, in the way offices collaborate, has taken place..

Bright Chest of DrawersThis project derives from a fascination of spaces which withonly light and shadow withhold a narrative value, which createsemotions and experiences with a minimum of objects. Iwanted to invesitigate light and lighting, and create a productthat can change the mood and experience of a spatial enviromentwith light. Questions I asked myself was: How do I relateto the spatial limitations that arise? How can I, with light asmy tool, give form to an immaterial value or state of mind?Will the object that illuminates be the most important factorof communication and meaning when I want to tell a story, oris it the light itself?The result became a chest of drawers that is lighted up frominside when you open the drawers. It serves a function as a unitfor storage of objects, but also makes us reflect of the importanceof objects, of how we define a spatial enviroment, andwhat we consider as private spaces in our home..

The aim of this study was to examine creativity, measured with four different tests, and self-image in 18-19 year old women (N = 30), and their earlier presence of imaginary companions. The result showed that there were many correlations between the different creativity measurements. Self-image correlated significant with fluency of ideas in one test. "Psychological health" along with "skills, talent and abilities" were the two most important self-image aspects for creativity. We found negative relationships between imaginary companions and creativity, but a positive relationship with self-image.

This study examines what effect swimming has on the rehabilitation, compared with only resting after a cranial cruciate ligament surgery. It consists of a literature study, an inquiry study and a visit to a rehabilitation centre. The inquiry study shows that ten weeks after a cranial cruciate ligament repair, the lameness has disappeared in a greater number of dogs among those that undergo swimming as physiotherapy compared with those that do not swim. Literature shows that swimming has a positive effect on the result after surgery. The thigh circumference increases faster, the limb function improves more and the range of motion gets larger. Dogs should therefore be recommended swimming as rehabilitation after surgery for a rupture of the cranial cruciate ligament..
